Audit Evidence
What is Evidence ???O Evidence : is any information used
by the auditor to determine whether the information being audited is in accordance with the established criteria.
Audit Evidence Decisions
1. Which audit procedures to use 2. What sample size to select for a
given procedure.3. Which items to select from the
population.4. When perform the procedures.
Audit ProceduresO Is the detailed instructions that
explain the audit evidence to be obtained during the audit.
O In specific terms.O EX : obtain cash disbursement
journal and compare the payee name,amout,and date on the cancelled checks.
Sample SizeO Sample size can vary from one to all
the items in the population.O The decision of how many items to
test must be made by the auditor for each audit.
O EX: 50 checks of 6600 recorded in the cash disbursement journal.
O The sample size for any procedure is likely to vary from audit to audit.
Items to selectO Selecting the 50 checks :1.Select a week and examine the first
50 checks.2.Select 50 checks with the largest
amounts.3.Select the checks randomly.4.Select those checks that the auditor
thinks are most likely to be in error.
TimingO The SEC requires that all public
companies file audited financial statements within 60 to 90 days of the company’s fiscal year-end.
Audit ProgramO The list of audit procedures for an
audit area or an entire audit.O It always includes a list of the audit
procedures, and is usually includes sample sizes, items to select and the timing of the test.
Persuasiveness of Evidence
O Two determinants:1. Appropriateness2. Sufficiency
Appropriateness O Is a measure of the quality of
evidence, meaning its relevance and reliability in meeting audit objectives.
1.Relevance of Evidence2.Reliability of Evidence
Relevance of EvidenceO Evidence must pertain to or be
relevant to the audit objective that the auditor is testing.
O EX : Auditor is concerned that the client is failing to bill customers(completeness transaction objective).
O What is the appropriate procedure ???
O If the auditor selects a sample of duplicate sales invoices and traces each to related shipping documents, is this evidence relevant ???
O A relevant procedure is to trace a sample of shipping documents to related duplicate sales invoices, to determine whether each shipment was billed.
Reliability of EvidenceO Refers to the degree to which evidence can
be believed or worthy of trust.O Six Characteristics of Reliable Evidence:1.Independence of provider2.Effectiveness of client’s internal controls3.Auditor’s direct knowledge4.Qualification of individuals providing the
information5.Degree of objectivity6.Timeliness
1. Independence of provider.Evidence obtained from a source
outside the entity is more reliable than that obtained from within.
EX: communication from banks, attorneys, or customers is more reliable than answers by the client.
2. Effectiveness of client’s internal controlsWhen internal controls are effective, evidence obtained is more reliable.3. Auditor’s direct knowledgeEvidence obtained directly by the auditor through physical examination, observation, recalculation and inspection is more reliable than information obtained indirectly.
4. Qualification of individuals providing the information.The individual providing the evidence is qualified.EX: communication with banks and attorneys.EX: auditor lacks qualification to examine an inventory of diamonds.5.Degree of objectivity. Objective evidence is more reliable than evidence that requires judgment.EX of objectives evidence : conformation of A/R and bank balances or the physical count of cash.EX of subjective evidence a letter from the client’s attorney discussing the likely outcome of and outstanding lawsuit.
6. Timeliness.Evidence is more reliable for balance sheet accounts when it is obtained as close to the balance sheet date as possible.
Sufficiency O Is measured primarily by the sample size
the auditor selects.O The quantity of evidence obtained
determines its sufficiency. O Factors to determine the appropriate
sample size :1.Auditor’s expectation of misstatement.2.The effectiveness of the client’s internal
control
O In addition to sample size, individual items tested affect the sufficiency of evidence.
O EX : sample containing items with large dollar amounts.
O Items with high likelihood of misstatement.O Items that are representative of the
population.
Combined EffectO The persuasiveness of evidence can
be evaluated only by considering the combination of appropriateness and sufficiency
O A large sample of evidence provided by an independent party is not persuasive unless it is relevant to the audit objective.

Persuasiveness and Cost
O The auditors goal is to obtain a sufficient amount of appropriate evidence at the lowest possible total cost.
Types of Audit Evidence1. Physical examination
2. Confirmation
3. Documentation
4. Analytical procedures
5. Inquiries of the client
6. Recalculation
7. Reperformance
8. Observation
Physical ExaminationO Is the inspection or count by the auditor of a
tangible asset.O Most often associated with inventory and
cash but can applicable to securities, notes receivable and intangible fixed assets.
O Is a direct means for verifying that an asset actually exists (existence objective).
O It is considered one of the most reliable and useful types of evidence.
O Used for ascertaining both the quantity and the description of the asset.
O Is not sufficient to verify that existing assets are owned by the client(rights and obligations).
O Not sufficient to verify (realizable value) or (accuracy).
Confirmation O The receipt of a written or oral response from
an independent third party verifying the accuracy of information that was requested by the auditor.
O They are from an independent source and so are highly regarded.
O Are costly to obtain and may cause inconvenience to those asked to supply them.
O Auditors typically obtain written responses rather than oral ones.
O Auditor must decide whether to use confirmation or not.
O Not used for fixed assets (physical examination and documentation) .
O Are not used to verify individual transactions between organizations such as sales.
O The auditor determines that there are 2 extraordinary large sales transactions recorded before balance sheet date, here confirmation may be used.
O Used for A/R.O They must be controlled by the auditor from
the time they are prepared to the time they are received.

Documentation O It is the auditor’s inspection of the
client’s documents and records.O Provide information of conducting
business.O May be in paper or electronic form.O Large volume of documents is usually
available.O Is widely used because its available at
low cost.
O Could be internal or External.O An Internal document has been prepared
and used within the client’s organization without ever leaving it. EX : employee time reports/duplicate sales invoices.
O An External document has been handled by someone outside the client’s organization.
EX: insurance policies/title of land.O External are more reliable why ???O Internal documents created under good
control.O Original better than photocopies.
Analytical ProceduresO Use comparison and relationships to
assess whether account balance or other data appear reasonable.
O Compare gross margin % of this year with the preceding year.
O Required during the planning and completion phases on all audit.
Purposes of Analytical Procedures
1- Understand the client’s industry and business.OAuditor must obtain knowledge about client’s industry and business as a part of planning an audit.OCurrent year’s unaudited information is compared with the prior year’s audited information or industry data.OChanges are highlighted.OThese changes can represent important trends or specific events which will influence audit planning.OEX : decline of gross margin percentage may indicate increasing competition.
Purposes of Analytical Procedures
2-Assess the entity’s ability to continue as a going concern.ODetermine whether the client company has financial problems.OHigher than normal ratio of long term debt to net worth is combined with lower than normal ratio of profits to total assets “indicates high risk of financial Failure”OThis will affect the audit plan and a report modification.
Purposes of Analytical Procedures
3- Indicate the presence of possible misstatements in the financial statements.OUnusual Fluctuations : significant differences between the current year’s unaudited financial data and other data used in comparison.OIf the unusual fluctuation is large the auditor must determine the reason and be satisfied that the cause is valid economic event and not a misstatement.OAllowance for uncollectible accounts compared to last year.OThis needs “Attention Directing”.
Purposes of Analytical Procedures
4-Reduce detailed audit tests.When there is no unusual fluctuations this means that the possibility of material misstatement is minimized.
Inquiries of the ClientO It is the obtaining of written or oral
information from the client in response to questions from the auditor.
O It is not from an independent source and may be biased.
O The auditor has to obtain additional evidence.
RecalculationO It involves rechecking a sample of
calculation made by the client.
ReperformanceO It is the auditor’s independent tests of client
accounting procedures or controls that were originally done.
O Information in the sales journal has been included for the proper customer at the correct amount in the subsidiary A/R and is accurately summarized in the general ledger.
ObservationO It is the use of the senses to assess client
activities.O The auditor may tour the plant to obtain a
general impression of the client’s facilities.

Cost of Types of Evidence
O Physical examination and confirmation the most expensive types of evidence.
Physical examination requires the presence of the auditor when the client is counting the asset.
Conformation must follow careful procedures in the confirmation preparation, mailing, and receipt.
Cost of Types of Evidence
O Documentation and analytical procedures are moderately costly.
If clients personnel locate documents for the auditor and organize them for convenient use, documentation will have low cost.
Analytical procedures are less expensive than confirmation and physical examination.
Therefore, most auditors prefer to replace tests of details with analytical procedures.
Cost of Types of EvidenceO The lest expensive types are observation,
inquires of the client and reperformance.

Documentation
Audit DocumentationO Audit documentation is the principal record
of auditing procedures applied, evidence obtained, and conclusions reached by the auditor in the engagement.
Purposes of audit documentation
1) A Basis for Planning the Audit.2) A Record of the evidence accumulated
and the Results of the Tests.3) Data for Determining the Proper type of
the Audit.4) A Basis for Review by supervisors and
partners.

Confidentiality O A member shall not disclose any confidential obtained
in the course of professional engagement except with the consent of the client.
Retention of Audit Documentation
O Auditing standards require that the records of private companies be retained for a minimum of five years.
